触发Outlook事件:更改签名 [英] Trigger Outlook Event: Change Signature

问题描述

有人知道在Outlook 2016中是否可能触发签名更改事件? IE.按照下面的屏幕快照模拟单击签名:

Does anyone know if it possible to trigger a signature change event in Outlook 2016? I.e. Simulate clicking a signature as per the screenshot below:

我正在尝试根据已选择的发件人"地址自动更改签名.我可以捕获发件人"地址的更改(在此处回答).

I am trying to change the signature automatically based on which 'From' address has been selected. I can capture the 'From' address change (as answered here).

但是，我找不到以编程方式更改签名的方法.我的研究得出的结论是，在Office 2016中不推荐使用CommandBar对象，并且需要与IRibbonUI对象进行交互.还是其他功能区对象?也许除了伪造按钮单击之外，还有其他更好的选择签名的方法?

However I cannot find a way to programmatically change the signature. My research has gotten as far as concluding that the CommandBar object is deprecated in Office 2016 and that I need to interact with the IRibbonUI object. Or perhaps some other Ribbon object? Or perhaps there is better way of selecting the signature other than faking a button click?

我无法在Outlook命名空间中找到Signature对象，并导致我得出这样的结论:MailItem类不了解签名-它仅了解正文.但是奇怪的是，我可以右键单击签名正文并打开一个上下文菜单:

I cannot find a Signature object in the Outlook namespace with leads me to conclude that the MailItem class does not know about signatures - it only knows about body text. However what is odd is that I can right-click on the signature body and bring up a context menu:

因此，某些地方 的某些对象必须了解签名-也许是电子邮件编辑器?

So some object somewhere must know about signatures - perhaps the email editor?

非常感谢

推荐答案

哇，好了，可以解决这个问题，但这是获得结果的一种round回的方式.感谢@niton的此方便的注释，为我指出了正确的方向.

Wow OK so figured this out but it is quite a roundabout way of achieving the result. Thanks to @niton for this handy comment to point me in the right direction.

总而言之，它执行以下操作:

In summary it performs the following:

• 更改MailItem中的SentOnBehalfOfName属性时引发事件
• 基于名为_MailAutoSig
的书签删除当前签名
• 根据选择的发件人选择html签名
• 插入html签名文件的内容并添加名为_MailAutoSig
的书签

• Raise event when SentOnBehalfOfName property in MailItem is changed
• Delete the current signature based on the presence of bookmark named _MailAutoSig
• Select the html signature based upon which sender was selected
• Insert the html signature file contents and add bookmark named _MailAutoSig

这是我到目前为止已实现的代码:

Here is the code I have implemented so far:

Dim WithEvents myInspector As Outlook.Inspectors
Dim WithEvents myMailItem As Outlook.MailItem

Private Sub Application_Startup()

    Set myInspector = Application.Inspectors

End Sub

Private Sub myInspector_NewInspector(ByVal Inspector As Outlook.Inspector)

    If TypeOf Inspector.CurrentItem Is MailItem Then
        Set myMailItem = Inspector.CurrentItem
    End If

End Sub

Private Sub myMailItem_PropertyChange(ByVal Name As String)
On Error GoTo ErrorCatcher

    Dim signatureName As String
    Dim signatureFilePath As String

    ' Properties we are interested in: "SendUsingAccount" / "SentOnBehalfOfName"
    ' Both get fired when the 'From' field is changed/re-selected
    ' So we are only going to trigger on one event or we will call the code twice
    If Name = "SentOnBehalfOfName" Then

        ' Delete the current signature
        Call DeleteSignature(myMailItem)

        ' Insert the new signature at the current cursor point
        ' The cursor will be at the point where the old signature was deleted
        signatureName = GetSignatureName(myMailItem.SentOnBehalfOfName)
        signatureFilePath = GetSignatureFilePath(signatureName)
        Call InsertSignature(myMailItem, signatureFilePath)

    End If

    Exit Sub

ErrorCatcher:

    MsgBox Err.Description

End Sub

Private Function DeleteSignature(objMail As MailItem)

    Dim objDoc As Word.Document
    Dim objBkm As Word.Bookmark

    Set objDoc = objMail.GetInspector.WordEditor

    If objDoc.Bookmarks.Exists("_MailAutoSig") Then
        Set objBkm = objDoc.Bookmarks("_MailAutoSig")
        objBkm.Select
        objDoc.Windows(1).Selection.Delete
    End If

End Function

Private Function GetSignatureName(sender As String)

    Select Case sender

        Case "Sender Name 1"
            GetSignatureName = "Signature 1"

        Case "Sender Name 2"
            GetSignatureName = "Signature 2"

        Case Else
            GetSignatureName = "Default"

    End Select


End Function

Private Function GetSignatureFilePath(signatureName As String) As String

    GetSignatureFilePath = Environ("AppData") & "\Microsoft\Signatures\" & signatureName & ".htm"

End Function

Private Function InsertSignature(objMail As MailItem, signatureFilePath As String)

    Dim objDoc As Word.Document
    Dim rngStart As Range
    Dim rngEnd As Range

    Set objDoc = objMail.GetInspector.WordEditor

    Set rngStart = objDoc.Application.Selection.Range
    rngStart.Collapse wdCollapseStart

    Set rngEnd = rngStart.Duplicate
    rngEnd.InsertParagraph

    rngStart.InsertFile signatureFilePath, , , , False
    rngEnd.Characters.Last.Delete

    objDoc.Bookmarks.Add "_MailAutoSig", rngEnd

End Function
